Dream team Installations / DSTV

Dream team installations installed an explorer at my house on 18/12/2018. The service provider called me to ask what I wanted in terms of the installation, I had 2 separate decoder supplying to 4 tv’s. I told the service provider that the exact same setup should be used as the work was done already , years ago and we never had any problems. The service provider advised that an additional R450 should be paid for the dual view , I accepted and paid the R450 cash. I arrived home after work to find that the service provider connected 2 tv’s in one living room and another in the main bedroom. The one decoder was disconnected and left as is. Not only did he disconnect the decoder but the tv in the main bedroom has very poor signal and at times go off completely. He used all my cable , I paid for installation and he used the old cables??? And please advise how to TV’s in one living room can be of any use???? Very poor workmanship!!! I tried calling the service provider +- 10 times , no answer. I also read on Hellopeter that the service provider never replies.
